REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 333,855, dated January5, 1886.

Application filed May 1, 1885. Serial No. 164,097. (No model.)

To all whom it may concern:

Be it known that I, BERNHARD HARTMANN, of Belleville, St. Clair county,Illinois, have invented a certain new and useful Improvement inSectional Refrigerators, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification.

Figure 1 is a perspective View with one side and part of the top of theice-chamber removed. Fig. 2 is a perspective view showing the inner sideof one of the sides. Fig. 3 is a horizontal section at 3 3, Fig. 4. Fig.4 is a vertical section at 4 4., Fig. 3. Fig. 5 is a detail view showingthe manner of securing in place the slats which form the bottom of theice-chamber.

A is the floor of the refrigerator, upon which stand the inner and outerwalls.

13 is a water'channel made in the floor, just within the inner wall, toprevent the water of condensation escaping between the floor and i thewalls in such a manner as to makedamp the sawdust or other packing withwhich the space between the inner and outer walls is filled. Thewater-channel 13 leads to a drain pipe, 0, which is let into the floorand extends from the channel to the outer side of the outer wall, wherethe water may have free exit or escape through a trap, D, as shown, toprevent the entrance of air. The inner wall is composed of foursections, E and E. The wall-sections E are made with cleats F near tothe upright edges of the sections, thus forming a rabbet-groove at eachof these edges, in which the corners of the sections E rest. Thesections E and E are secured together at the corners in any suitablemanner. For this purpose I show hooks and eyes G and H, attached to thedifferent sections, respectively. The sections are strengthened orstiffened by ribs I and J, secured to the outer sides, and the uprightribs I are fastened to similar ribs, 1, upon the inner sides of theouter walls by means of hooks K and eyes L, or by any other suitablemeans. The outer walls are composed of sections arranged in much thesame manner as the inner walls, there being a space, M, between thewalls. which is filled with sawdust or any other suitable packing tocheck the entrance of heat into the inner chamber, N.

O is a cover which is secured by screws or other means to the top of thewalls E E, so as to form a top to the ice-chamber P. The bottom of theice-chamber is composed of slats or bars Q, upon which the blocks of iceare placed and between which the cold air and water descend into thechamber N, which contains the articles to be kept cool. These slats aredovetailed at their extremities into the horizontal supporting-cleats Q,whereby said slats are not only held against displacement themselves,but aid materially in bracing and holding the side sections, E E. Theouter walls consist of sections R and R, fitted together at the corners,and there secured by hooks S and eyes T, or by any other suitable means.

U andVare hinged doors closing doorways in one of the walls E, and U Vare doors in the outer walls section S, in line with the doors U and V,respectively. By means of the doors U U access is had to the chamber N,and by the doors V V to chamber P.

The wall-sections E E R R are described and shown as each consisting ofa single part; but where the refrigerator is of considerable size eachof these wall-sections may be made of two or more parts connected byvertical joints.

These refrigerators are, it will be seen, portable, and they areintended for a more or less temporary use. By this construction theparts may be readily separated and conveniently transported from placeto place.

I claim 1. Arefrigerator having an inner and outer case, whose uprightwalls are composed of sections engaged together at the vertical corners,and having stiffening-ribs I and I between the corners, engagedtogether, substantially as set forth.

2. An inner case having wall-sections E E, and containing lower chamber,N, and icechamber I, an outer case having wall-sections R R, and a floorhaving a water-channel communicating with a discharge-pipe extendingfrom the inner chamber to the outside of the refrigerator.

3. The two cases E E and R B, one within the other, and the lower andupper openings through the sides of the cases, with doors U U and V V,closing in the planes of the sides, 6.
